Answer 1

Answer:

answer is C please mark as brainlist and follow me

Answer 2

The a.c supply cannot be used for electroplating.

Explanation

• An alternating current cannot be utilised for electroplating also because ac polarity of something like the battery changes with time, causing the ions that must be deposited on the surface [for electroplating] to oscillate back and forth within the electrolyte, prohibiting electroplating.
• Electroplating is the method of putting a very thin layer of another metal on a metal or metal item using a direct electric current. The metals are partially dissolved, and a chemical link is formed between them. Electroplating produces a layer that is typically 0.0002 inches thick.
